Thanks Kougar, I'm on-board for a space thread.
Emerging technology is ramping up and its cool to see space exploration interest growing again. I've visited NASA's Kennedy and Johnson Space Centers and the Smithsonian Air and Space Museum in DC. Such a fascinating period in history and I always hope NASA operations will continue with strong support.
I'm interested in the NASA Near Earth Object Search studies because odds are another Tunguska-type event is likely to happen anytime:https://www.youtube.com/watch?v=EiXpp-i442s
Not if but when? Luckily it was in a remote area.
The meteor exploding over Chelyabinsk, Russia was a close call about this time 5 years ago (15 Feb 2013) and was unexpected out of the clear blue:https://www.youtube.com/watch?v=dpmXyJrs7iU
Personally over the years I've witnessed a few fireball bolides
light up the night sky on different occasions as they broke apart on atmospheric entry.
Hopefully pro-active searching, identification and preventive measures will improve with new technological advances.
